Overview

The DFX-23A-II portable electric sputum suction machine occupies the most compact and energy-efficient position in Keling Medical's DFX-23A series. With a 50 VA power draw — approximately one-third that of comparable models — and a lightweight one-piece ABS housing, it is particularly suited to prolonged bedside use, home nursing environments and settings where power consumption or weight are critical considerations.

Free air flow of ≥15 L/min and an adjustable negative pressure range of 0.013–0.07 MPa provide effective suctioning of sputum and other secretions for patients with moderate secretion volumes. The macromolecule (medical-grade polymer) 1×1000 ml suction bottle removes easily for disinfection and cleaning between uses, supporting infection control protocols in both clinical and home settings. An integrated overflow protection device keeps the maintenance-free oil-free piston pump safe from fluid contamination even if a caregiver fails to empty the bottle before it reaches capacity.

Operating at ≤55 dB, the DFX-23A-II generates minimal noise during suctioning — an important quality for patients undergoing extended treatments or those resting between sessions. The simple ON/OFF and vacuum adjustment controls on the front panel require no specialist training, making the unit accessible to home caregivers as well as nursing staff.

Quick facts

Questions buyers ask

What is the Keling DFX-23A-II electric sputum suction machine used for?

The DFX-23A-II is a compact portable aspirator for clearing sputum and thick secretions from patients' airways in hospitals, clinics and home care settings. Its ≥15 L/min flow rate and 0.013–0.07 MPa vacuum range are appropriate for patients with moderate secretion volumes requiring regular aspiration.

How does the DFX-23A-II differ from the DFX-23A-I model?

The DFX-23A-II has a lower power input (50 VA vs. 150 VA), a slightly lower maximum vacuum (0.07 MPa vs. 0.08 MPa) and a lower free air flow (≥15 L/min vs. ≥18 L/min). This makes the DFX-23A-II the more compact, energy-efficient choice for lighter-duty use, including home nursing environments.

What suction bottle does the DFX-23A-II use?

The DFX-23A-II uses a 1×1000 ml macromolecule (medical-grade plastic) suction bottle that is easy to detach, disinfect and clean between uses, supporting infection control in both clinical and home settings.

Can the DFX-23A-II be ordered in bulk or exported internationally?

Yes. Keling Medical supplies hospitals, distributors and export customers worldwide via its Shanghai export center. Contact Keling Medical at https://www.kelingmed.com for pricing, bulk purchasing terms and export documentation.
